Google fails utterly when it comes to searching for exact strings.

I've found a thing that extracts Outlook emails to .eml format.  When I open it in TextPad, I find a bunch of weird things in the message.  Here, help me decode this (apostrophes surround literal text):

'=3A'   =   ':'
'='   =   return
'=1B$B!H=1B(B'   =   '“'
'=1B$B!I=1B(B'   =   '”'
'=3D'   =   '='

That's what I have so far.
